Answer:

Step-by-step explanation:

Given

distance crawled by the snail = 6cm = 0.06m

Time taken = 0.75minutes = 0.75*60

Time taken = 45secs

Required

constant rate of change of the snail's crawl (speed)

Speed of the snail = distance/time;

Speed of the snail = 0.06/45

Speed of the snail = 0.00133m/s

Hence the constant rate of change of the snail's crawl in m/s is 0.00133m/s

Segment AB has and endpoint at A (2,5) and a mod point at M (4,0), find the other endpoint (B).

steposvetlana [31]

Answer:

The other endpoint B= (6, -5)

Step-by-step explanation:

Given:

One end point A= (2,5)

Mid point M = (4,0)

To Find:

The Other point =?

Solution:

According to midpoint formula, if (x1, y1) and (x2, y2) are two ends of a line then it’s midpoint is given by :

$M(x,y)= \frac{x1+ x2}{2} ,\frac{y1+ y2}{2}$

Using the above formula

$4=\frac{2+x_2}{2}$ ..................................(1)

$0=\frac{5+y_2}{2}$ ..................................(2)

Solving equation(1)

tex]8=2+x_2[/tex]

$x_2=8-2$

$x_2=6$

Solving equation(2)

$0\times 2=\frac{5+y_2}{2}$

$0=5+y_2$

$-5=y_2$

Thus $x_2=6$ and $y_2 =-5$

Find the value of x. Round to the nearest tenth. 9 4 x = [?]

schepotkina [342]

Answer:

26.4° (nearest tenth)

Step-by-step explanation:

$\boxed{sinθ = \frac{opp}{hyp} }$

$sinx = \frac{4}{9}$

<em>Taking the inverse of sine on both sides:</em>

$x = sin^{ - 1} ( \frac{4}{9} )$

x= 26.4° (nearest tenth)
